I have a problem in statics that I must use excel to do and my instructor modified the given question in a few ways to allows to use the capabilities of excel to find what the question asks for.

If the whole excel approach sounds confusing then please help in solving the original question. That way I can use that method in solving the question the way my instructor expects.

In class today I was given an extension on this problem.

I also found that the free body diagram that I was using was a little complicated and the only forces acting on the handle is the applied force and the force caused by the spring. I'm a little confused in how to find the force caused by the spring and which [tex]\Sigma F=0[/tex] and [tex]\Sigma M=0[/tex] equations to use.
